<p>Hey <span class="user-mention" data-user-id="123586">@nagisa</span> <span class="user-mention" data-user-id="133224">@Nikita Popov</span> -- we raised the idea of a WG oriented around </p>
<ul>
<li>improving how we use LLVM</li>
<li>improving LLVM itself to address bugs</li>
</ul>
<p>Still interested in pursuing this? If so, there are <a href="https://github.com/rust-lang/compiler-team/blob/master/procedures/form-new-working-group.md#step-3-setting-things-up" target="_blank" title="https://github.com/rust-lang/compiler-team/blob/master/procedures/form-new-working-group.md#step-3-setting-things-up">instructions in the compiler-team repository</a> for how to setup the basic template, and I can create the Zulip stuff.</p>

<p>I, too, am too tied up by other things to pitch in. But in my biased opinion, this is indeed an area where it would make sense to focus more contributions, so I'd be very happy to see such a WG happen and would gladly offer braindumping/mentoring/etc. as time permits</p>

<p>I think <span class="user-mention" data-user-id="124289">@rkruppe</span> / <span class="user-mention" data-user-id="123586">@nagisa</span>  the "minimal initial investment" that probably makes sense for a WG is a set of leaders / mentors who are willing to do the following:</p>
<ul>
<li>Create a few specific actionable ideas that would be good candidates</li>
<li>Monitor the Zulip stream and mentor folks who show up</li>
<li>Update the compiler team every once in a while</li>
</ul>
<p>I don't think it has to be a super high investment, but that first step is sort of key. It seems ok to me if we create a WG, do some work to setup "mentorable bugs", and then step back to steep if a few folks show up. We can avoid creating too many bugs in order to avoid a flood. =) If nobody shows up, that's ok, we're no worse off -- better off, even, as we have some mentorable bugs in the queue for later.</p>
<p>But if writing decent mentoring instructions on 1-3 bugs is too much work, it's probably not worth it.</p>

<p>I guess first order of business (if we want a list of mentorable issues) is then to find issues that stem from LLVM we want to fix the most. <code>loop {}</code> is an obvious candidate I had in mind when proposing the WG, but that is something I already started working on... I guess I could write up <em>some</em> instructions mayhaps?</p>

<p><code>loop { }</code> would be great, yeah. I don't know <em>how</em> detailed the mentoring instructions have to be -- even outlining some high-level steps and asking people to find you for more in depth comments would be better than nothing</p>

<p>I know that I'd definitely be interested in helping out with this working group - I have zero experience with LLVM but with some high level instructions and a pointer or two about which areas of the code I should be looking at then I'd be happy to dive in and see what I can come up with.</p>
